Hi I have an Z800 second hand, just bought it and everything was fine for about 2 months but after that it started to boot loop while its cold and morning after few times of restart it turns off again an when I start again it works but this happens almost everyday. Sometimes it shuts down while first boot, I'm not sure what is it but I don't know could this thing harm my pc

Keeping your components cool is in general beneficial. The problem can be caused by your power supply unit. Can you borrow another one and swap ot just to test?

Experienced the same when I had a failing power supply, so as Zoltan suggest here, borrow a new power supply.

zoltan.boese i already send my pc to tech repair but they said that nothing was wrong with components, also i said look at power supply but they said that power supply had no problems and they said that everything was working fine and i got my pc at my home again but after 2 weeks problem repeated

If the workshop was unable to recreate and examine the problem, you could try and plug your pc into another electric outlet in a different room.
